61 During the tests of coal pyrolysis in plasma producing acetylene, the signals of system are acquired, showed, restored and controlled in real time is very important.

62 The modified xylok resin was subsequently blended with glass cloth and acetylene black to generate a new conductive composite.

63 This thesis is concerning the acetylene produced through co - cracking coal and natural gas by plasma jet.

64 Acetylene induced decline in nitrogenase activity was found only in the healthy (unstressed) nodules, but not in the stress treated nodules.

65 About 85% of the enterprises in our country which use fuel gas take use of acetylene gas.

66 The preparation of 5A zeolite supported platinum catalyst, and its catalytic capabilities for hydrosilylation reaction of acetylene with triethoxysilane were studied.

67 Please contact our technical service department if your applications involve interaction with oxygen or acetylene gases.

68 From the aspects of technology and economics, advant ages of high - energy gas fuel in place of acetylene are analyzed and compared.

69 Yedan, oxygen, nitrogen, acetylene gas, acetylene sales; Chemical products, metal Dianliao, plumbing materials, supplies wash sales.

70 The results of acetylene reduction detection showed that 88.5 % were effective for nitrogen fixation.

71 The remaining 20 % of the acetylene production is principally used for oxyacetylene cutting, heat treating, and welding.

72 Acetylene (ethyne)Simplest alkyne, C2H2. A colourless, flammable, explosive gas, it is used as a fuel in welding and cutting metals and as a raw material for many organic compounds and plastics.

73 The Frankia isolates grown in N - deficient BAP medium exhibited an acetylene reducing activity.

74 Moreover, in order to rationalized these fragmentation processes, the bimolecular proton-bound complex between benzyne and acetylene intermediate has been proposed.

75 And there are 8 kinds of main components in liquid fuel, which belong to higher olefine hydrocarbon, acetylene series, heterocyclic compound and polycyclic organic matter.

76 The source made a breakthrough the idea that air acetylene flame emission spectrometry was used for determination of alkali and alkali earth elements only.

77 As vinyl chloride synthesized from acetylene and hydrogen chloride is further converted into polyvinyl chloride, mercuric chloride must be made use of as a catalyst and activated carbon as a carrier.

78 Usage:It is the raw material of organic synthesis and calcium Cyanamide. It can produce acetylene gas, and can be used as Deoxidizer for steel making and cut metal.

79 Therefore, new technology of using acetylene sludge to calcine clinker will be discussed in this article.

80 Flame forming technological property of titanium alloy plate is investigated with the oxygen acetylene heating. Sentencedict.com

81 In the high - pressure system both oxygen and acetylene are used from high - pressure cylinders.

82 The acetylene gas generated by calcium carbide can be applied to weld or cut metal materials.

83 The green production processes in substitute of ACH mainly include isobutene processes, ethylene processes, isobutane processes and methyl acetylene processes, which will be discussed in this paper.

84 With vinyl acetate as reactant in place of acetylene and its derivates in 1,3 dipolar cycloaddition, the target product was obtained successfully.

85 Weight ( not pressure ) is used to determine the amount of acetylene in a cylinder.

86 The hazards of higher alkynes held up in acetylene concentration system were presented.

87 Can detect hydrogen, oxygen, nitrogen, carbon monoxide, methane, dioxide, ethylene, ethane, acetylene and other gases.
